Forget what I said. I confused the "signature" field in the Type class with
the attribute "Signature". No code in BCEL will need to be changed. Unless
you want to add a a generator for generic type signatures. So I got things
working like this basically:
FieldGen fg;
fg.addAttribute(new org.apache.bcel.classfile.Signature(
cp.addUtf8("Signature"), 2,
cp.addUtf8(typeToVMSignature
<http://code.botcompany.de:8081/tb/show-snippet.php?id=1035321>(type)),
cp.getConstantPool()));
It really helps to talk about problems in a forum, lol.
My Java-based scripting language is coming along very nicely now.
Have a nice day
